I thought they used nails, screws and bolts for rockets. I was thinking the marbles were for the wrist rockets they had. (sling shots) There was plenty of evidence that this was not a “humanitarian” mission.

RE the marbles, yes Avid’s observations make sense. The presence of slingshots were probably a cover for their real purposes. One question…wouldn’t the marbles turn into glass dust in an explosion? I don’t imagine they’d be as effective as ball-bearings, nails and bolts…would they? Why would they use marbles instead of small metal objects??
